This tutorial will guide you on how to install the device drivers for USBasp programmer for Windows 7 or VistaNote:1. This installation procedure is same for all USBasp devices regardless of where you have purchased your programmer from or made it yourself. 2. The device driver mentioned here is partially signed. This essentially means that Windows will warn you but still install it. 3. Windows 7 and Vista do not install unsigned drivers until driver signature enforcement is disabled at boot time (obviously a not very good option)

The USBasp programmer has been made been designed by Thomas Fischl to program Atmel’s AVR series devices. ROBOGYAN is in no way connected to the individuals or organizations mentioned in thisdocument

Select --> Browse my computer for driver softwareYou will see a window like this:

Now browse to the location where you have unzipped the downloaded folder (in step 1) and select USBasp-win-driver-x86-x64-ia64-v1.2.4

Don’t forget to check the “include subfolders” box and then click next STEP 5:You will get this warning message

Select “Install this driver software anyway”Note: This step is what makes this installation different from the previous versions. Windows 7 and Vista do not install unsigned drivers until the driver signature enforcement is disabled at boot time (which would obviously compromise the safety of your system) .Rest assured, you can safely install this driver version since it is partially signed. And then……………………………Voila!!!So now you have this magic screen
